Digital Cellular Phones

Overview
For digital cellular phones, information such as
• the base stations that can be contacted
the phone numbers of the base stations and
•
• the type of protocol to be used
can be defined.
Changing the base station to be dialed is of interest in two cases.
Case 1: Two real-time base stations, each equipped with a digital
cellular phone, are set up at two locations belonging to dif-
ferent network providers.
When leaving the area of one base, the station can be
changed and the other base can be called.
Case 2: Set up as in case 1.
Two separate fixes from each base for each point can be
obtained, providing redundancy for future least squares
adjustment operations.
Technology Description
CDMA Code Division Multiple Access is a high speed data transmis-
sion for effective and flexible use of available resources such
as bandwidth. Users of a cellular phone network occupy the
same frequency band. The signal is especially coded for each
user.
GSM Global System for Mobile Communications is a more efficient
version of CDMA technology that uses smaller time slots but
faster data transfer rates. It is the world's most commonly
used digital network.
